【产品】超低电容TVS二极管阵列，提供±8 kV接触ESD保护
LITTELFUSE公司推出了一系列集成了3线超低电容的二极管阵列——SP7522T，能够为可能遭受破坏性静电释放（ESD）冲击的电子设备提供保护功能。该系列二极管属于高可靠性器件，可在不产生性能衰减的情况下，防范超过IEC 61000-4-2 ±8 kV接触ESD等级静电释放的冲击。
SP7522T系列二极管阵列具有低漏电电流和低电容的优点。在5V条件下，它的漏电电流最大为50nA。在3GHz条件下，每个输入/输出电容的典型值为0.15pF，超低的负载电容使它成为保护V-by-OneR、HDMI、USB3.0、USB2.0和IEEE 1394等高速信号引脚的理想之选。该系列二极管还具有一定的湿度灵敏性，湿度灵敏性的等级 为MSL-1。
SP7522T的实物如图1所示，无卤素和无铅，符合RoHS标准。它主要应用于V-by-One®、嵌入式显示器端口、USB 2.0/3.0端口、HDMI、串行总线接口、平板显示器、液晶/LED电视、智能电话以及移动计算等领域。
